Immediate Relief for Common AC Issues

When an air conditioner fails, it rarely happens at a convenient time. Homeowners often ignore minor signs of distress until the unit completely shuts down. Addressing these symptoms early can prevent catastrophic failure and expensive component replacement. Our technicians arrive equipped to handle the specific cooling challenges found in McMillan, where humidity levels can make even moderate heat feel unbearable.

One of the most frequent issues we encounter is a lack of cool air despite the system running. This often indicates a restricted airflow issue, a clogged air filter, or low refrigerant levels due to a leak. Simply adding more refrigerant without fixing the leak is a temporary solution that violates environmental regulations and wastes money. We locate the source of the leak, repair the brazed joint or connection, and recharge the system to manufacturer specifications.

Electrical issues also plague many residential systems. If your AC trips the breaker repeatedly, it is a safety mechanism preventing an electrical fire or motor burnout. Continually resetting the breaker without diagnosing the short circuit or grounded compressor can destroy your electrical panel or the AC unit itself. We inspect capacitors, contactors, and wiring connections to ensure the electrical load is managed correctly.

Strange noises act as early warning signals. A squealing sound often points to a slipped belt or a motor bearing needing lubrication. Grinding noises usually indicate a more serious issue with the motor or compressor. Hissing implies a significant refrigerant leak or high internal pressure. Our team isolates these sounds to the specific component, allowing for targeted repairs rather than guesswork.

Our AC Services—Fast, Reliable, and Thorough

We provide a holistic approach to air conditioning, moving beyond simple fixes to ensure the longevity and efficiency of your cooling system. A functioning AC unit does more than lower the temperature; it manages indoor air quality and humidity.

Diagnostic and Repair Services

Our repair process begins with a comprehensive system evaluation. We do not just swap parts; we analyze the entire refrigeration cycle.

• Refrigerant Level Check: We measure superheat and subcooling to ensure the refrigerant charge is exact. Incorrect charging reduces efficiency and increases wear on the compressor.

• Airflow Analysis: We check static pressure in your ductwork. High static pressure restricts air, causing the blower motor to work harder and the evaporator coil to potentially freeze.

• Component Testing: We test the capacitance of start and run capacitors. A weak capacitor is a leading cause of compressor failure.

• Condensate Drain Cleaning: clogged drain lines can cause water damage to your home and trigger safety float switches that shut down the unit. We clear and treat these lines to prevent algae growth.

System Maintenance and Tuning

Preventative maintenance is the difference between a system that lasts 10 years and one that lasts 20. In the damp climate of British Columbia, outdoor units are susceptible to debris accumulation and corrosion.

• Coil Cleaning: Dirty condenser coils cannot release heat effectively, forcing the system to run longer cycles. We chemically clean these coils to restore heat transfer capabilities.

• Electrical Tightening: Vibrations loosen electrical connections over time. We retorque all connections to prevent voltage drops and overheating.

• Thermostat Calibration: We ensure your thermostat reads the temperature accurately, preventing short-cycling that wastes energy.

Your Path to a Cooler Home: Our AC Installation Process

Installing a new air conditioner is a construction project that requires precise engineering. A poor installation will compromise even the highest-rated equipment. We follow a strict protocol to ensure your new system performs at its peak efficiency from day one.

Sizing and Load Calculation

We never guess the size of the unit based on the previous equipment. We perform a Manual J load calculation that considers:

• The square footage and layout of your home.

• Insulation levels in the attic and walls.

• Window orientation and solar heat gain.

• Internal heat sources like appliances and electronics.

This ensures the unit is not too small (which causes it to run constantly) or too large (which causes it to short-cycle and fail to dehumidify).

Site Preparation and Equipment Removal

• We disconnect and reclaim old refrigerant according to environmental safety standards.

• We remove the old unit and inspect the concrete pad. If the pad has settled or cracked, we level or replace it to ensure the new unit sits flat, which is vital for compressor lubrication.

• We inspect existing ductwork for leaks or damage that would undermine the new system.

Installation and Brazing

• We position the condenser and indoor evaporator coil.

• We connect the copper refrigerant lines. Crucially, we flow nitrogen through the lines while brazing. This prevents oxidation and soot from forming inside the pipes, which could later clog the metering device.

• We install a new filter drier to trap moisture and contaminants.

Commissioning the System

• Pressure Testing: We pressurize the lines with nitrogen to ensure there are no leaks at the braze joints.

• Evacuation: We use a vacuum pump to remove air and moisture from the lines, achieving a deep vacuum (typically below 500 microns). Moisture in the system creates acid that eats away at motor windings.

• Final Charge and Test: We release the refrigerant and fine-tune the charge based on outdoor temperatures and indoor wet-bulb readings. We verify the temperature drop across the coil to confirm cooling capacity.

Deciding Between AC Repair and Replacement: What You Need to Know

Homeowners often struggle with the financial decision of whether to repair an aging unit or invest in a modern replacement — check our current promotions. Rep-Air Heating and Cooling helps you navigate this choice using clear metrics rather than sales pressure.

• The Age of the System: Most air conditioners have a lifespan of 12 to 15 years. If your unit is approaching or has surpassed this range, major repairs are rarely a wise investment. Parts for older units become scarce and expensive, and the likelihood of a secondary failure increases significantly.
• The Cost of Repair vs. System Value: We recommend the "50% Rule." If the cost of the repair approaches 50% of the value of a new system, replacement is the more economically sound choice. For example, replacing a compressor in a 12-year-old unit is rarely cost-effective compared to putting that money toward a new system with a 10-year warranty.
• Refrigerant Type: Older systems utilize R-22 refrigerant, which has been phased out due to environmental regulations. R-22 is now extremely expensive. If your older unit has a leak, the cost to recharge it often rivals the cost of a down payment on a new, eco-friendly R-410A or R-454B system.
• Energy Efficiency and Technology: Newer air conditioners are significantly more efficient. Moving from a 10 SEER unit to a 16 SEER2 unit can reduce cooling bills by 30% to 50%.

• Single-Stage vs. Variable Speed: Older units are typically single-stage (on or off). Modern variable-speed compressors can ramp up or down to match the cooling load, providing consistent temperatures and superior humidity removal without the noise and energy spikes of starting and stopping.

• Smart Integration: New systems integrate seamlessly with smart thermostats, allowing you to control climates remotely and track energy usage.

Adhering to McMillan's Building Codes and Seasonal Recommendations

Operating in this region requires specific attention to local regulations and climate patterns. An AC installation is not just a plug-and-play appliance; it is a permanent fixture subject to municipal oversight.

• Permits and Inspections: Proper permitting is non-negotiable. It ensures that the electrical circuits are sized correctly for the amperage of the new unit and that the installation meets safety standards. Unpermitted work can complicate future home sales and may void manufacturer warranties. We handle the administrative burden of pulling permits and scheduling required inspections.
• Climate-Specific Considerations: While summers are warm, the local climate is defined by wet winters and significant rainfall.

• Rust and Corrosion: The outdoor condenser unit sits in the elements year-round. We ensure units are elevated on composite pads or snow legs to keep them out of standing water and debris.

• Dehumidification: In our region, "it's not the heat, it's the humidity" is a factual statement. An AC system must be calibrated to remove moisture effectively. If a unit is oversized, it will cool the air too quickly and shut off before it has had time to dehumidify the space, leading to a cold, clammy indoor environment.

• Shoulder Season Maintenance: Because the AC sits dormant during the long, wet winter, scheduling maintenance in early spring is critical. This ensures that rodents haven't chewed wires and that the fan motor hasn't seized up from months of inactivity before you need the system on the first hot day.
